'Trumpet' in the Bible

It came about when he had arrived, that he blew the trumpet in the hill country of Ephraim; and the sons of Israel went down with him from the hill country, and he was in front of them.

So the Spirit of the Lord came upon Gideon; and he blew a trumpet, and the Abiezrites were called together to follow him.

When I and all who are with me blow the trumpet, then you also blow the trumpets all around the camp and say, ‘For the Lord and for Gideon.’”
